Barack Obama inherited a set of national-security policies that he rejected during the campaign but now embraces as president. This is a stunning and welcome about-face.
For example, President Obama kept George W. Bush's military tribunals for terror detainees after calling them an "enormous failure" and a "legal black hole." His campaign claimed last summer that "court systems . . . are capable of convicting terrorists." Upon entering office, he found out they aren't.
